I bought a pair of these microphones because I use them at my previous church because they are so great at isolating sound. We used them on Easter Sunday for a choir of 20 people right next to a drum kit. They did a fantastic job of amplifying the choir group without ringing out. Highly recommend at this price point!

Who has heard of Studio Projects any more? What a shame! I've owned a bunch of matched SDC pairs, but always wind up selling them off. I love these mics, especially on my Kawai grand piano. They are so beautifully transparent and uncolored. I was messing about in the studio today and micing the piano. Nothing seemed to be working. I set up the C4s and immediately, "Ah! That's my piano." Can't say enough good about these little beauties!

These mics worked well for me, when they worked. I take good care of my equipment and house it in a climate controlled room. I never even really worked these mics too hard (they're not my go-to SDCs). After 5 years though now all I get is white noise and strange popping sounds out of them. Only a very small amount of signal is coming through. It isn't my recording equipment as I have tested on various other mics and all is working fine.

To date, this is the only piece of equipment I've ever had fail. If these were cheaper than I would have been fine with them dying, but at the price they charge I would expect lightly used and well cared for microphones to last far beyond 5 years. I will never purchase another Studio Projects piece of equipment, and I wouldn't encourage anyone else to do so.

I used these as overheads while tracking drums not expecting much but ended up with surprisingly good results. There is a little harshness on the high end but when used through good equipment and a little EQ, this is not a big issue. I'd recommend these to anyone looking for decent room/overhead mics at a good price.

This is a great "poor man's 451" microphone, a true workhorse in my project studio. I use it with the cardioid capsule for drum overheads & percussion, and with the hyper to close mic acoustic guitar, ukulele, mando. It's not as nicely defined and detailed as a 451 of course, but this is an awesome pair of mics in that vein for two-thirds of the price. Solid mics and best bargain out there!

I've had these mics for a while, used exclusively with the stereo bar in ORTF formation for drum overheads. They work great for that. Then this past weekend I had a bunch of group female vocals to sing and decided to employ them for that through my Apollo- wow our minds were truly blown by the insane realness of the stereo image to the point where people were confused on playback thinking people were still singing in the room. Madness! The way they slide into a mix with the lead vocal is also just so natural but with great separation, they sit right where you'd like them. Try these for group vocals (if you can manage to snag a pair). You'll be amazed.

I use the C4's to record guitar duos and overhead drums and percussion in stereo. I think they are fantastic with a rich bottom end, warm mids, clear top end but not harsh or strident. If you experiment with placement you can achieve clear and balanced stereo recordings. Love 'em.

I just got the mics and had a little home project to do using my Boston baby grand piano. Set them up based on what I'd seen on one of the Sweetwater videos and first takes were gold. Several other takes required but not due to the mics.

BTW - I used my Studio Project B1 for the vocals - very sweet.

I don't like writing negative reviews, but I feel obligated to share my experience when it might help others make informed purchasing decisions. I purchased the kit a few years ago before they changed the finish and added the hypercardiod capsules. Perhaps the newer versions have improved. I picked up a few Studio Projects mics at the recommendation of friends and because the are priced well. I've had major issues with them and don't trust them anymore. For some reason, I have major noise and output issues with certain capsule combinations. The problem is, there are not consistent. I've tried multiple pre-amps and field recorders with these mics and found that I was getting a strange frequency sweep artifact with the Zoom H4n.

When they work, they sound great. When they don't, I'm not pleased.

It's hard to beat this kit. A pair of great-sounding small diaphragm condensers just by themselves could arguably be worth the asking price, but throw in two additional capsules per mic, and two-setting pad and high pass switches. Whoa! But wait, would you also like a stereo bar with that? Super Sweet!!!

I have to say, my only small disappointment is that these mics and all the components do not come in a hard case. I would pay extra for that feature. There's a padded soft bag included, but it's not nearly big enough to jam all these components into.

Still, awesome value.

glad that I bought these. I had an opportunity to test them against a pair of sm137's. I couldn't tell much difference when used as drum overheads with the cardiod tip. The omni tips pick up a lot of low end too. Guitar amps had a good growl.

Bought a pair of these because we wanted stereo capability. The build quality is fantastic and they are loaded with features that you would double the price to get. We have a large diaphragm Studio Projects mic that we were able to mod with a U67 Capsule clone. The Schoeps electronics inside are open and clear. I'm not sure if these mics have the same guts, but they really sound great. Give them a shot with a UAD Pultec and hear the magic

I purchased this to replace a mic that retailed at over $800 and I am thrilled and impressed that I am getting such comparable quality. I teach high school video production and we use this microphone for group interviews. It really serves our purpose well. The interchangeable capsules also add to the versatility of the microphone. I am so happy that I purchased these.

These mics sound great, and provide a decent budget-minded alternative to a pair of Neumann KM-184's. There are a few odd things, though. First, the "matched pair" microphones come in plastic bags with stickers containing sequential serial numbers. The mics themselves are not marked with serial numbers, so if you buy more than 2 (as I did) it's easy to get them mixed up so the "matched pairs" (if they even really are) are no longer matched. Second, after a couple of months, the diaphragm assemblies in 2 of my 4 mics have begun to rattle when the mics are moved. I haven't noticed any difference in the sound of my recordings, but it's a bit disconcerting. Are they falling apart? Third, the included mic clips are too tight, and can cause the little SP logo medalions to pop off very easily, requiring them to be super-glued back in place. Lastly, the "wooden" (read: plastic) box included with each pair is really just for show, is not that well padded, and is much larger than it needs to be, making for inconvenient carrying/transport.
I'd recommend these mics for their sound, but given all the "little things" listed above, I'm not sure how long they'll last.

I got these to use to capture a stereo image and planned to augment the recording of other mics that were dedicated to specific instruments, but found that much of the time an X-Y configuration of these is more than good enough. Nice and quiet and very well matched. Cheaper than just one of the other small condenser mics I have, and so far, these are the ones that I rely on. If you don't have a matched stereo pair, these are a good choice.

A very nice pair of mics. They sound great and are very versatile. The build quality is cheap and mine didn't come with one of the hyper-cardioid. Studio Projects has made it very easy to get the capsule sent to me with no hassle. So that makes me feel good about the service. Obviously low QC though.

I would buy them again. I like them more than the NT5 matched pairs for ambient recordings. They aren't Neumann, but for the price they certainly are nice.

So I needed some pencils, and it was between these and the Rode NT5's. I went with these for two reasons; price and function. I liked the fact that these came with two capsuls (omni, cardiod). I also really wanted the roll off, as Im using these mostly as cymbal mics, its almost essential to me. And of course the db pad is a nice plus. I would imagine the NT5's probably sound a little better, and I'll likely end up buying those too in the next year. But for right now, money is an object, so these came first. Now in terms of sound...

They're pretty detailed, a little bright, but not shrill. They're pretty good quality, I'd say they sound very similar to Shure KSM137, maybe not quite there, but close. So if you're looking for good overheads at an amazing price, I give you my blessing.

Also, mine came in a VERY nice cherry wood case, where all my other mics are in a filing cabinet draw, these are on display on my desk.

With abundant capsule (omni or cardioid) and pad/rolloff options, these mics have stunned me in only 3 sessions. I've heard them likened to 'human ears', and that's a fair assessment. If your room is less-than-ideal, you can close it off with the presure-gradient caps. If you want your living room in the recording WITH the piano, the omnis will give you just that. Warm, bright but not brittle, these mics will serve you well on piano, vocals, drum OHs, and many other applications.

The C4 set is a great pair of microphones. I've used them on drums, acoustic guitar, ambience mics, and also some experimentation with the omni capsules. They sound good. Period. Very versatile, very clear, but without sounding sterile. I have yet to be disappointed by any mic from Studio Projects. They all have had fantastic sonics and a really decent price. The C4 package continues that trend.
